natural aromatase inhibitors for men

In addition, a man’s body increases aromatase activity when men have sudden increases in androgen levels. This includes taking testosterone therapy or supplements that increase this hormone. The increase in aromatase is the cause of many of the unwanted side effects of androgen therapy, including gynecomastia, moodiness, impotence, infertility, and a decrease in testicular size. In the Breast International Group’s Femara-Tamoxifen trial, also known as BIG 1–98, 5 years of adjuvant letrozole was compared with 5 years of tamoxifen in postmenopausal women with ER-positive and/or PgR-positive breast cancer. Eventually, this trial was modified with the addition of two treatment groups in which women were either switched from tamoxifen to letrozole or from letrozole to tamoxifen after the initial 2 years of treatment (26).

Understanding the Complexity of TRT

The conundrum some men face is that estrogen levels tend to increase as testosterone levels do. As part of the steroidogenesis pathway, testosterone is metabolized into either dihydrotestosterone (DHT) by the 5-alpha reductase enzyme or estradiol by the aromatase enzyme. These case reports illustrate the important contribution of estrogens to male health and identify the possible indications and risks of aromatase-inhibitor treatment in men. They may be used to increase gonadotropin secretion and thereby stimulate Leydig and Sertoli cell function. Aromatase inhibitors may be used to prevent or delay epiphysial closure and thereby increase adult height.

Aromatase inhibition restores testosterone levels in hypogonadal older men

Using aromatase inhibitors can also affect men’s metabolism and cardiovascular health. These changes can be significant and may require lifestyle adjustments or medical interventions to manage effectively. Decreasing Estrogen, such as by consuming https://acgcardservices.net/steroids-pharmacological-understanding-their-role-14/ natural aromatase inhibitors, can improve many different diseases and symptoms, such as Asthma, Dementia & Alzheimer’s, Depression & Anhedonia, and Hypothyroidism. A deficiency in magnesium increases aromatase, and most people are deficient in this nutrient.

Because of their effectiveness, AIs are quickly becoming the most frequently used antihormonal treatment for breast cancer in postmenopausal women. Aromatase inhibitors are widely prescribed for hormone-responsive breast carcinoma in postmenopausal women. It is well known that aromatase inhibition results in a dramatic reduction of tumor estrogen concentrations 66. As gynecomastia in men presumably results from an imbalance between androgen and estrogen action, aromatase inhibition was tested as a treatment for gynecomastia in boys.

However, the consequences of aromatase expression in the human brain remain poorly understood. In healthy male volunteers, anastrozole has been shown to increase adiposity, particularly in the intraabdominal compartment (13). Aromatase inhibitors are widely used for long-term treatment in breast cancer, but any effect on fuel metabolism has not been addressed. In postmenopausal women, estrogen replacement reduces the risk of type 2 diabetes mellitus (6). Estrogens are generated from substrate androgens through the action of the cytochrome P450 enzyme aromatase (7). It is possible that the metabolic phenotype in androgen-deficient men is largely a consequence of downstream estrogen deficiency.

Given the importance of E2 in male physiology and the impact of TTH on E2, careful monitoring by practitioners providing exogenous therapy is critical. This retrospective study in Indian males showed insignificant effect of AI in gynecomastia and IHH, significant effect in CDP and some benefit in improving seminal parameters. Moreover, this study highlights the importance of estimating E2 (along with T and gonadotropins) in various endocrinopathies, which can be benefitted by reducing E2 by AI. Therefore, inhibiting beta-glucuronidase (via calcium D-glucarate) may help lower levels of estradiol and estrogen metabolites by increasing their rate of elimination 17. So the less aromatase you have, the more testosterone is allowed to remain in its free form.

• Blocking testosterone from transforming into estradiol may help to boost free testosterone levels.
• Though yet to be fully explored, olive oil shows potential in boosting the effectiveness of other aromatase inhibitors.
• When aromatase inhibitors reduce estrogen levels, several side effects can arise.

Several ongoing clinical trials are examining the use of AIs in women at an elevated risk of developing breast cancer. Critical to the ultimate success of AIs in both the adjuvant and preventive settings will be management of adverse events, particularly bone mineral density loss, arthralgias and gynaecological sequelae. In men and postmenopausal women, local generation and action of estradiol in adipose tissue and skeletal muscle is likely to be more physiologically relevant than distant action. Plasma concentration of estradiol does not necessarily reflect tissue concentration, as evidenced by the similar breast tissue levels observed in pre- and postmenopausal women, despite markedly divergent plasma concentrations (37). It would be desirable to directly assess the effects of aromatase inhibition on target tissue sex steroid hormone concentration.

The following section will break down the research highlighting naturally occurring compounds that act as estrogen blockers. Research suggests the common table mushroom has anti-aromatase22 properties and therefore possible anti-estrogen activity. Chinese women who consumed mushrooms and green tea had a 90% lower incidence of breast cancer.23 However the study was relatively small (2,018 patients participating) and limited to Chinese women of southeast China.

A 2018 study in the Journal of Clinical Oncology also noted that the risk of diabetes was 240% greater in women on aromatase inhibitors than in the general population. Although the risk was far lower with tamoxifen, aromatase inhibitors do not pose the risk of thromboembolism (blood clots) or endometrial cancer that tamoxifen does. Women on aromatase inhibitors are at a two- and four-fold increased risk of bone loss compared to a matched set of women in the general population, says a 2015 review in the Journal of Bone Oncology. The long-term effects of aromatase inhibitors are arguably more concerning. Unlike tamoxifen, aromatase inhibitors tend to speed up osteopenia (bone loss) in older women who are already at risk of bone problems. Aromatase inhibitors are not effective in premenopausal women unless they are combined with ovarian suppression because they mainly inhibit the estrogen produced in the fat tissue and not in the ovaries.
